To all lwhom t may concern:

Be it known that I, ALFRED HANNAroRo, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hog Scrapers and lonveyers, of which the following is a speciication.

This invention relates to improvements in hog scraping and conveying machines, and

the primary object of the invention is to provide an improved machine of this character for rapidly and thoroughly removing the hair, bristles and dirt from the carcass.

A further object of the invention is to provide a hog-dehairing machine having powerdriven and rotarily acting flexible scraper-mechanism and coperatively powerdriven and rotarily-acting conveyer mechanism adapted to freely and completely sup- )ort the carcass and at the same time roll 1t laterally and advance it longitudinally while presenting it to the simultaneous dehairing-action of the scraper-mechanism, without said carcass being grappled to the said or other advancing means, the said carcass being free of any grappling to any advancing means.

A further object of the invention is to provide an improved scraper which will also convey or advance the carcass through the machine.

A further object is to provide an improved support for the carcass which also serves to convey the carcass through the machine.

A further object is to provide an improved Ispiral conveyer for supporting and advancing the carcass, and improved scrapors secured to the conveyer.

A further object is to provide an iniproved spiral conveyer and scraper for the carcass and improved scrapers coperating therewith and arranged transversely of the line of travel of the carcass through the machine.

A further object is to provide improved means for feeding the carcass to the machine.

A further ob3ect is to provide an improved scraper and conveyer and improved means for polishing the carcass when scraped.

A further object is to provide an improved scraper and conveyer and a plurality of yielding Scrapers coperating therewith and arranged transversely of the line of travel of the carcass through the machine.

A further object is to provide an imroved machine of this character which will e sinple, cheap and durable in construction and e ective and eiicient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists 1n the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the-accompanying drawings illustrating an exem- Iphfication of the invention, and 1n which- Figure 1 is a side elevation of an improved machine of this character constructed in accordance with the principles of this invention. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a sectional view on line `3--3 of Fig. 1. Fig. 4 is a detail sectional view of the improved conveyer and scraper. Fig. 5 is a detail sectional vlew of a portion of the polishing mechanism. Fig. 6 is an elevation of one of the scra ers. Fig. 7 is a top plan view of Fig. 6. 4ig. 8 is a diagrammatic view showing the relative positions of the conveyer and scraper and supporting drum and the conveyer for removm I the hair from the top of the tank. Fi 9 1s a detail view of one of the iexible po?- ishing members. Fig. 10 is a longitudinal sectional view partly in elevation of a modified form of polishing mechanism. Fig. 11 is an end elevation of Fig. 10.

Referring more particularly to the drawings and in this excmplification of the invention,the numerals 10, 11 designate spaced parallel drums which are journaled between suitable uprights or frames 12, 13. These drums may be of any desired length and diameter and are arranged in the same horizontal plane. The drum 10 is preferably provided with a smooth periphery and the drum 11 is constructed of any suitable flexible material, such as heavy wire, or the like, coiled to form a spiral having spaced convolutions, the ends of the wire being secured to suitable heads 14, as shown more clearly in Fig. 4 of the drawings. The axle 15 of the drum 11 preferably passes through the am, au

center of the drum and extends 'beyond the heads\14 so that the drum 11 will form a' tlexibleor'yielding support for the carcass when it rests thereon, and4 also serve as means for taking up the jzrr on the axle or bearings when the carcass is dumped by the drum in a manner'v to be hereinafter set forth.

Secured to the convolutiohs of the spiral 11 are detachable scraping devices or blades 16 which are arranged throughout the entireV length of the spiral and project beyond 'the periphery of the drum 11, being spaced from the drum 10 to permit .the drums to rotate without the scraping devices contact-ing with theperiphery of the other drum. These scraping devices or blades 16 may be secured in position in any desired or suitable manner,` preferably by means of suitable U bolts 17 which stand astride of the respective convolutions, with -the extremities passing through the base 18 of the scraping deviceslG, and the Scrapers and bolts may be secured in position by suitable nuts 19 engaging the free ends of the bolts. These sera ing devices are disposed transversely of t e respective convolutions and diagon'ally with relation thereto, as shown more 1 vclearly in Figs. 4 and 7 of the drawings.

Secured to'one end-of the axles of the respective drums is a suitable sprocket '-.ivheel 20,"and passing over said sprocket wheel is v'an endless chain or belt 21 for simultaneous'ly rotating the-drums in the direction indicated by the arrows in Fig. 8 of the drawings. A Arranged adjacent the forward end ofthe drums is a suitable scalding tank 22 which is preferably provided with an inclined extremity 23V in close proximity to the ends of,

to and depositingit upon the incline or chute 24;, The conveyer or elevator 25 may be operated from, the shaft 26 to which motion is imparted by means of a driving sha-ft -27 through the medium of a belt orchain 28.

The rearframework 13' preferably extends some distance above the tops of the drumsV 10 and 11, and is located in close proximity tothe other ends thereof. Pivotally supportedtg the'reafr frame 13 and by 4 one ,end thereof are a. pluralityof spaced.

armsf29, 30, 3,1, 32. The, pivot'ed ends of these lrms are preferably: superposed with relation to each other, and the arms are of such a lengththat the free ends thereof will terminate adjacent? the tops of the drums Arranged between each of the respective pairs of arms are yielding scrapers33, 34, 35, '36, each of which is preferably constructed o-a suitable piece ot flexible material 37, such as wire or the like, coiled or bent to form a spiral having spaced convolutions, and these Scrapers are journaled between the-respective pairs of arms by means ot suitable axles extending beyond the ends of the Scrapers andv resting in suitable'bearings in the arms. The arms 29 areof such a length that the scraper 33 supported thereby will stand in close proximity to the topsI of the drums 10, 11, adjacent the forward end thereof, and the remaining arms are of.

such a relative length that the respective" scrapers 34, 35, 3G will be arranged behind the scraper 33 and in the same longitudinal and horizontal plane and will normally stand adjacent the peripheries of the drums 10 and 11. Secured to the convolutions of the spirals 37 of each of the Scrapers are a plurality of spaced scraping devices 38,

which are similar in construction to the scraping devlce 16 and are secured to the Iconvolu't-ions of the spirals 37 ina similar manner, so as to project beyond the peripheries-thereof. These Scrapers 33, 34, 35 and 36 are arranged to extend transverselyacross the space formed between the drums 10 and l1, and any suitable means may be provided :for holding the Scrapers out of contact with the peripheries of the drums, such as brack= :ets 39, which may be secured to the framework 13, and which are' adapted to be enf gaged by the arms '29, 30, 31and 32. Se-

cured to each of the shafts of the respecitive Scrapers 33, 34, 35, 36, is a sprocket wheel 40, shown more clearly in Fig 1 of the drawing, and secured adjacentthe other ends of the respective arms is a sprocket 41.

.Passing around the respectiye sprockets 'at the extremities of thev arms is al sprocketl chain 42, by means of which the respectlve Scrapers may be rotated in a direction op- -fposed to the direction .of the advancement of the carcass by means of the drum or conveyer 11.-- Secured to the sha-ft which supports the respective sprockets 41 isa similar sprocket 43, and passing around these sprockets 43 is a sprocket chain 44 which serves to vsimultaneously rotate the sprockets 40. Motion may be imparted to the re,- speetive. scraper-s through the medium o'f 4sprocket chains 42, and the sprocket wheels 41, sprockets 43, sprocket chain 44, by means of a suitable sprocket chain 45 engaging a sprocket 46 on one of the supporting shafts of the sprockets v41 and-a suitable sprocket wheel 47 secured to the drivingshaft 27.
